Article Synopsis
- The research focuses on the Higgs mode in a strongly interacting Fermi gas transitioning from a fermionic to a bosonic superfluid.
- By adjusting the interaction strength of the gas, the researchers excite the Higgs mode and measure its resonance frequency and line width based on different interaction strengths and temperatures.
- They discover that at low temperatures, the resonance frequency aligns with a theoretical model, and both frequency and line width remain relatively stable with temperature, contrary to theoretical expectations but in line with another recent study.
We determine the phase diagram of strongly correlated fermions in the crossover from Bose-Einstein condensates of molecules (BEC) to Cooper pairs of fermions (BCS) utilizing an artificial neural network. By applying advanced image recognition techniques to the momentum distribution of the fermions, a quantity which has been widely considered as featureless for providing information about the condensed state, we measure the critical temperature and show that it exhibits a maximum on the bosonic side of the crossover. Additionally, we backanalyze the trained neural network and demonstrate that it interprets physically relevant quantities.
